结构不同的咪唑并[1,2- a ]吡啶[2',1':2,3]咪唑并[4,5- c ]喹啉衍生物和苯并[4,5]咪唑[1,2- a ]吡啶[2 ”,1' :2,3]咪唑并[4,5- c ^ ] -喹啉衍生物已经由2-(2-溴苯基) -咪唑并[1,2制备一个]吡啶-3-甲醛在一维壶,分两步进行,收率达到优良(50-85%)。这些π扩展化合物的光物理性质(吸收和发射)和溶剂致变色现象受到赞扬。唑基咪唑并[1,2- a ]吡啶显示出高荧光发射,量子产率中等至良好。
An efficient one-pot protocol has been developed using sequential C-N coupling and intramolecular dehydrogenativecross-couplings for the synthesis of azole fused imidazo[1,2-a]pyridine derivatives in good yields (62-78%).
